Hello everyone, I'm from Mexico I would like to know where I can download the manual for a G4X or G4 + Xtreme? I have only found the G4 manual and I see that a lot has changed in the software I am new to this topic and I am evaluating which ECU I will buy, I have read that in addition to buying the G4X or G4 + Xtreme ECU I have to consider buying "Ballast Resistor" in case of using low impedance injectors or buying "Link Bosch EV14 1000C Injector" Could you help me with the download link for the g4X or g4 + Xtreme manual Or tell me if I have to buy something else I still don't know which engine I'm going to use, that's why I thought about the ECU G4X or G4 + Xtreme But surely it would not be any engine found in the ECU Plug In Greetings
